IP40 vs IP62
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP40 and IP62 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 6) and liquid protection (level 0 vs 2). IP40 is rated for > 1 mm — small wires and no protection, while IP62 provides dust-tight and dripping water at 15° tilt.
IP40 protects against small tools and wires (1 mm objects) but offers no water protection. Useful for indoor equipment needing finer ingress protection against small debris and tools.
Built to withstand dust-tight (no ingress of dust) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. Classified as IEC 60529 ingress protection code IP62, it pairs solid level 6 with liquid level 2.

The exact difference (IP40 vs IP62)
Solid protection
IP40
Level 4 — > 1 mm — Small Wires
IP62
Level 6 — Dust-Tight
IP40 provides "> 1 mm — Small Wires" (level 4), while IP62 provides "Dust-Tight" (level 6). IP62 is 2 levels higher.
Liquid protection
IP40
Level 0 — No Protection
IP62
Level 2 — Dripping Water at 15° Tilt
IP40 provides "No Protection" (level 0), while IP62 provides "Dripping Water at 15° Tilt" (level 2). IP62 is 2 levels higher.

Recommendation
IP62 offers higher overall protection than IP40. Choose IP62 for harsher environments; IP40 may suffice for milder conditions and can be more cost-effective.
